Herb Paris + Cefdinir

Cefdinir brand name: Omnicef.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 20, 2026
The bottom line No known interaction

We found no known interaction between Herb Paris and Cefdinir in our sources. Absence of a documented interaction is not the same as proven safety, and does not guarantee one does not exist. Do not start, stop, or change a medication or supplement based on this page; confirm with your pharmacist or doctor first. Additionally, although there is no interaction, the two are separately associated with some of the same side effects, which would make a new symptom harder to attribute to one or the other.

Herb Paris and Cefdinir

We checked these two against our interaction database. Here is what we found.

No Known Interaction Found

We did not find a documented interaction between Cefdinir and Herb Paris in our sources. This does not guarantee that the combination is completely free of risk — there is often limited research on supplements and herbal products, especially around drug interactions.

Worth understanding: our licensed dataset holds no drug-interaction record for Herb Paris at all — not against Cefdinir, and not against any other medication we track. This verdict therefore rests on the absence of any recorded data, not on research that looked at this combination and found nothing. We cannot rule an interaction out.

If you decide to take both, the practical routine is simple: add one new thing at a time and note the date you started it. If the combination is going to disagree with you, it usually shows in the first days to a couple of weeks — and a start date turns “I’ve been feeling off” into something a pharmacist can actually work with. Do not stop a prescribed medicine on your own.

Always talk with your pharmacist or doctor before making changes to your medications or supplements, particularly if you take several medications or have an ongoing health condition.

What to actually watch for

No Interaction Found — But Data Suggests Herb Paris and Cefdinir May Share Several of the Same Side Effects

This is not an interaction. Neither one changes how your body handles the other, and nothing here says they react together. What our sources do show is that each has separately been linked to the effects below — so taking both can make those effects more likely to turn up, and harder to pin on one or the other if they do.

Everything else you take

See Every Supplement That Interacts With Cefdinir

This page covers Herb Paris only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Cefdinir page lists 60 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Asarabacca (major), Siberian Cocklebur (major), African Wild Potato (moderate) and Aristolochia (moderate).

By severity: 3 major · 46 moderate · 11 minor.

From our pharmacist’s overview on the Cefdinir page

“Cefdinir (Omnicef) is a short-course antibiotic for ear, sinus, throat, and skin infections, and three of its 60 supplement interactions on file are rated major and deserve genuine care. Two herbs, Siberian cocklebur and asarabacca, can damage the kidneys, an added strain nobody needs while fighting an infection.”

About Herb Paris

What is Herb Paris?

  • Headache and migraine (traditional/homeopathic use)
  • Nerve pain and neuralgia
  • Eye complaints (folk use)
  • Cough and bronchitis (folk use)
  • Inflammation and swelling (traditional use)

Herb Paris (Paris quadrifolia) is a poisonous woodland plant that has been used historically in folk medicine and is sold mainly in highly diluted homeopathic forms. There is no reliable scientific evidence that it treats any health condition, and the raw plant is toxic, so it should not be self-prescribed. Talk to a pharmacist or doctor before using any product containing it.

Paris quadrifolia · Melanthiaceae · Whole herb, rhizome (root), berries, and leaves · Homeopathic preparations (pellets, dilutions); rarely as dried herb

An interaction check asks whether these two react with each other — it does not ask whether Herb Paris is a good idea for someone in your situation. Here is what our Herb Paris record says about it on its own.

Herb Paris: dosing

There is no established safe or effective dose of Herb Paris. The raw plant is toxic, so it should not be self-dosed at all. Homeopathic products come in standardized dilution labels (such as different "C" or "X" potencies), but these reflect homeopathic convention rather than proven dosing.If you choose to use a commercial product, follow the directions on the label exactly and do not exceed them.

About Cefdinir

What Is Cefdinir Used For?

Brand name: Omnicef

Cefdinir treats mild to moderate bacterial infections in adults, adolescents, and children caused by susceptible bacteria. It is used for community-acquired pneumonia, acute exacerbations of chronic bronchitis, acute maxillary sinusitis (sinus infection), pharyngitis/tonsillitis (strep throat), and uncomplicated skin and skin structure infections.

In pediatric patients (ages 6 months through 12 years), cefdinir is also used to treat acute bacterial otitis media (middle ear infection). It should only be used for infections that are proven or strongly suspected to be caused by bacteria — not for viral illnesses like the common cold.

Most-Reported Side Effects for Cefdinir

From FAERS, the FDA’s public side-effect reporting system (7,629 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Diarrhea 530 reports
Chronic kidney disease 485 reports
Pneumonia 482 reports
Fatigue 462 reports
Nausea 400 reports

Yes — our sources link each of them separately to 4 of the same effects. That is not an interaction: neither changes how your body handles the other.
